Fire guide device of coke oven ascending pipe as well as working method thereof

Abstract

The invention relates to a fire guide device of a coke oven ascending pipe as well as a working method thereof. A top outlet of the ascending pipe is positioned below a coke oven dust-removing cover;the ascending pipe is provided with a water sealing cover; the water sealing cover is driven by a water sealing cover executing mechanism to open and close; the fire guide device consists of a fire guide pipe, a fire guide pipe cover and a fire guide pipe cover executing mechanism; the fire guide pipe is positioned over the ascending pipe; the top of the fire guide pipe penetrates through the cokeoven dust-removing cover and is provided with the fire guide pipe cover; and the fire guide pipe cover is driven by the fire guide pipe cover executing mechanism to open and close. The coke oven dust-removing cover can be prevented from being roasted by flame generated by combustion of rude gas in the ascending pipe, high-temperature smoke dust escaped from the ascending pipe under the accident state is guided out of the coke oven dust-removing cover, and the aim of protecting the coke oven dust-removing cover is fulfilled; in addition, reverse forced ventilation can be realized through the fire guide pipe, the explosion risk caused by the fact that a large amount of combustible gas is accumulated in a coke oven area under the accident state can be avoided, and the fire guide device is suitable for various working conditions.

Description

technical field [0001] The invention relates to the technical field of coking and dust removal, in particular to an ignition device for a riser pipe of a coke oven and a working method thereof. Background technique [0002] The coking industry is an important industry related to the lifeline of the national economy. It has developed rapidly in recent years, but the serious environmental pollution problems caused by coking production have become increasingly prominent. During the coke oven production process, smoke and dust will escape from the furnace door, furnace roof coal charging hole, and fire viewing hole, and a large amount of intermittent pollutants will also escape into the atmosphere during coal charging, coke discharge and other production links. The escaping smoke contains gas containing tar and a large amount of dust, which will cause great harm to the surrounding environment. With the continuous improvement of the country's environmental protection requirement...

AI Technical Summary

Problems solved by technology

However, in this technical solution, the top of the coke oven is completely sealed by the dust removal cover, and the riser is also inside the dust removal cover. Long characteristics, and each coking cycle will appear

Not only that, sometimes the water seal cover will be forced to open in the event of an accident, and a large amount of high-temperature smoke and waste gas will escape from the coke oven riser and directly burn the inside of the dust removal cover. The existing heat insulation measures cannot effectively protect the dust removal cover. , will cause the dust cover to be deformed by heat, or even burned
